Specification of Letters Patent.

Original application filed April 4, 1910, Serial No. 553,330. Divided and this applicationfile d August 17,

To all whom it may concern:

Be it known that I, CLIFTON F. LEATHER.- BEE, a citizen of the United States, residing atNewton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Conveyers, of which the following is a specification. 1 v p The present invention relates to conveyers and more especially to the-provision of an improved form of apparatus which may be employed in handling and disposing of material of considerable length, such as flooring, strips of molding, cross-arms and like strips 'or lengths of material issuing from the machine adapted for the application of paint, stain, varnish, creosote or preservative substance, coating of insulation material and the like.

The principal objects of my present invention are the provision of a machine characterized as above noted, which is adapted to receive the treated material as it issues from the treating or coating machine and convey it either forwardly or laterally to a drying apparatus or other means of disposition; to provide improved means for removing the'treated material from the ma chine and keep it exposed to the atmosphere for a certain period of time to the end that it may be more readily handled; to provide means for preventing, as far as possible, contact of thetreated material with the conveyer and consequent marring of the treated surface or soiling of the conveyer, or both;

the provision of improved means for trans ferrin'g the material from the conveyer moving in one plane to that of a conveyer moving in another plane, as well .as certain further objects as will hereinafter more fully appear. Other features of my present invention are more fully set forth and claimed in my copending application Serial No. 553,330, filed April 4, 1910, l-ofwhich this is a division.

In the attainment of the objects above set forth, together with such additional ad- 1910. Serial No. 577,624.

vantages as may .bebelow disclosed, I have provided a construction, preferred embodiment ofwhich is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of a preferred form of conveying and elevating mechanism utilized by me; and

Fig. 2 is an end elevational View of a portion ofthe'apparatus of Fig. 1, part of such apparatus having been removed and part being shownin'section taken on the line II-II ofFig. 1, and

Fig. 3 is an of construction. 1

Referring now 'more particularly to Fig. 1, itfwill be observed that I have shown my improved conveyer arranged for use in con nection with, a coating machine indicated diagrammatically at 3, arranging, at one end of such coating machine .a belt conveyer 4; and at the opposite end of the conveyer 4 a secondary belt conveyer 5 parallel to which is placed an elevating conveyer 6, to the end that as the treated material issues from the machine 3, it is deposited on one end of the belt conveyer' l, thence discharged upon the secondary belt conveyer 5 disposed on a lower plane, and thence delivered to the elevating conveyer 6, in order that delivery of the material from the machine upon the drier conveyer 21 may not interfere with the actionof the device by means of which the attendant of the machine 3 removes the material for drying from the'conveyer 4: to the conveyer 6.

The belt 5 is provided at .intervals with cleats 7-7, preferably of inverted V-shape, disposed transversely thereof, for purposes of preventing contact of the treated surface of the material issuing from the machine 3 with such belt and consequently marring of such treated "surface or soiling of the belt, or' both, as the material is moved laterally therefrom, and to provide ways upon which theremoving device now to be described may slide freely.

The removing device, as may be clearly elevational view of a detail Patented Oct. 2, 1917.

and lowering mechanism now to be described.v

Referring now more particularly to Fig.

2,'it'"wi11 be observed that from the ntry a the material passes onto one of the sets of fingers l8 prnvided at intervals o n the longitudinalme nbers l9' here shown as pi'pes) supperted at each end upon links ,of :thefend less chain 20 engaging sprockets indieated at .22 22 one of the upper sprockets 2 22 ,F;ig. 2') is drivenintermittently from .the shaft 23, which has suitable clutch driving connections, to the hulo .of thespro'oket 24 and is driven frorn the motor25 ,ofthetreating machine through a sprocket. 24 mounted on saidshaft23; a pair ofsprockets.63Pifi3 on the shaft 68 which carries "the pulling wheel Mfldrivingthe conveyer 4; a sprocket 63 on the shaft of the driving .motorr25 of the treating machine 3, chains 61 and 641 connecting said several spreekets and the several eonveyers and .the treating maeh ne being thereby driven in unison.

I The 'sp roc k et 2&1 is adapted to drive by means .of 'the chain 25, a sprocket .26 ,oa rried ontheshaft 27 .whiehin turn by means of a worm 28 drivesa gear29 lreyedonihe sha ft 30, whichcarries the sproclzet 2lil It is to be understoodlthat. the pipes 19 are mounted against" rotatien relatively to the chain .20 by any suitable'means.

As is clearly to .be seen on viewing Fig. 2, there is disposed oppositely to each of the fingers 1,8,a finger provided with a bent portion 33, the purpose of such construction being that asthe material. is turned, during the progress of the elevating mechanism in tie directien indicated by'the arro w" ig. 2 and thence drops away from eontact with the fingers 18, it is restrained by such fingers $2 from falling or disengagement from the chain 11111111 in its descent it' co nes in Contact with the guides34and thence discha f-gfi l from the elevating and lowering mechanism uphn the floor or suitable means for disposing of By virtue of the travel of the treated n aterial and the manner of handling it iherein described, it will apparent that 'yvhen ui k d y n Li id -e 1 m d a riea ieeii such material has an opportunity .to Joe con e {thoroughly ,dried by the ti i efit dis.-

charged upon the guides 34: for further disposition; also that it is so discharged with the unpainted side down, and may be moved away for shipment or storage without abrasion of the unpainted portion through contact with the floor.

As 'a'means for giving a step by step movement to the elevatingmechanism shown on plan in Fig. 1 and side elevation in Fig. 2, that :is, allowing it to move only the distancebetween two ofthe series ,offingers 18, on a single impulse, I have provided clutch mechanism and operating means therefor whereby the sprocket 24: may be caused to tinovewithithe shaft 23 or remain stationary relatively thereto.

"means for imparting intermittent motion comprises as here shown a rocking lever 10 mounted upon the actuating ,rod 11, at one ,end as indicated at 4e 1, .aiidf ait the other end pivoted iudieated at etZto the clutch hotuating rodflflg v\vhieh terminates in. a' hifurc ated portion. a l engaging a euiwied collar 5L5 on, the shaft Aic tuatiqn of t e rod 11 in the rlirectiQnl indicated by the arrow (Fig. 1h moves the rod 43 the .tli etien ndi ated by th a ow ,(F sfer ces the collard?) to the right against the @0116 a mar e in r-' 1s .r f s-tl face ,of the gone to the night and thereby th nvi e' in he mu h el iqh'an s 48' a fixing ,the sprocket 24; against rotationon the shaft l23,, thus causing such shaft to drive Said sprocket 24- and move .the ,con-

I v v I For the purpose of allowing a ready automatic opening ,of the elutoh by simple incohanism, the'yoke 456 is carried the support member 59, vhieh has a tripping deviee 6Q pivot-ally mounted thereon and provided with .a screw 61 wherebylthe angularity of the mounting of the tripping device relatively to thesupporting lever 'may he yanied and the respeetive endsof the fingers 1.8 and of the guides 1:7 bebr eught into position and ali nedto insure ,the delivery of the material fro mithe guides o the fingers .up un the actuation ,of the removingdevice bythe lever 10.
